FIELD: petroleum processing. SUBSTANCE: process is conducted in pyrolytic coiled pipes protected by heat-resistant coating with thermal expansion coefficient close to that of basic material of pipes. Enamel is based on IIA, IIIB. IVB, and VIA group metal oxides and is modified by IIA, IVA. VB, VIB, and VIII group metal oxides and supplemented with filler made up of IIA and IIIB group metal oxides. EFFECT: essentially reduced coke-formation rate and simplified pyrolytic decomposition product technology due to diminished equipment downtime and diminished number of uncoking operations. 7 cl, 1 dwg, 1 tbld
